T at whom it may concern.-

Be it known that 1, JOHN BOYD, a subject of the Queen of Great Britain and Ireland, and a resident of Glasgow, in the county of Lanark, Scotland, have invented certain Improvements in Cop-Building Mechanism for Spinning andAnalogous Machines, (for which I have obtained British Patent No. 4,593, dated March 16, 1889,) of which the following is a specification.

My said invention comprises an improved combination of mechanism for lifting and lowering the building or traversing rails of spinning, roving, twisting, and analogous machines, the said mechanism being powerful, compact, and comparatively simple, and not liable-t0 derangement.

Mechanism made according to m y invention is shown in the accompanying explanatory drawings, in which- Figure l is aside elevation; Fig. 2, an end elevation Fig.[3,a separate elevation of a part not fully seen in Fig. 2 Fig. 4, a horizontal section, and Fig. 5 a sectional face view of certain internal parts. Fig. 6 is a vertical sectional view,

In the drawings the same reference-numerals are used to mark the same or like parts wherever they are repeated.

The mechanism shown in the drawings is in part carried by a casting 6, bolted to a transverse frame 7 of a spinning or other machine. The building or traversing rails, of which a part 8 of one is shown in the drawings, are lifted and lowered by means of vertical racks 9, acted on by pinions 10 on alongitudinal shaft 11, and I prefer to have the racks of some of the rails acted on by one pinion-shaft in front of the pinions and the racks of the other rails behind the pinions, so that the rails and other parts may counterbalance each other. The racks are formed on or fixed to tubular carrying-slides 12, fitted to move vertically on stationary guide-rods 13 and having the building-rails 8 fixed to them. In Fig. 3 the rack is shown as fixed or formed on a looped part 14 of the slide 12, so as to gear with the inner side of the pinion 10, while those slides which have the rack formed or fixed so as to gear on the inner side of the 1 pinions may be made without the looped part 14. At one end the pinion-shaft 11 extends through a bearing 15 in the fixed casting 6, which is made with a ring 16 of internal teeth concentric with the shaft, and the shaft, extending farther, has loose on it the boss 17 of a bevel-wheel 18, this boss being eccentric and having loose on it the boss 19 of an inner wh'eel 20,made with external teeth to gear with the internal teeth 16 of the fixed casting 6. The rotation of the bevel-wheel18 and its eccentric boss 17 carries the inner wheel 20 round; but in consequence of its teeth meshing with the fixed internal teeth 16 it turns in the opposite direction to the bevel-wheel 18 to an extent depending on the difference between the number of its teeth and that of the fixed internal teeth 16. The rotation of the inner wheel 20 is communicated to the pinion-shaft 11 by means of a cross-bar 21, formed or fixed on said shaft, and which engages in a slot or groove in a plate 22, this plate being made with arms at right angles to its slot or groove, which arms are fitted to slide between projections 23 on the inner face of the inner wheel 20. This arrangement forms what is known as a diiferential motion, whereby a reduction of speed is obtainable and parts of it may be transposed or modified with similar results.

The bevel-wheel 18 hereinbefore referred to gears with two opposite bevel-wheels 24 25, which are loose on a driving-shaft 26 at right angles to the pinion-shaft 11, the shaft 26 being driven in one direction in some cases direct from, say, the feed-roller shaft of a spinning or twisting machine. The two bevel-wheels 24 25 are made with clutch-faced bosses to engage alternately with a clutchsleeve 27, which is between them, and is driven by the shaft 26 by means of a groove and feather. The clutch-sleeve 27 is grooved externally, so as to be movable by pins on the fork-arms of a lever 28, which is loose on a spindle 29, the latter having fast on it two levers 3O 31, one 30 of which is in a position to be acted on by adjustable lower and upper tappets 32 upon a bracket 33, fixed to the building or traversing rail 8, the lower tappet lifting the lever 30 on the rail approaching its highest position and the upper tappet lowering the lever on the rail approaching its lowest position. When the lever 30 is being lifted,-it causes the other lever 31, fixed on the same spindle 29, to bear against one of two revcrsely-inclined surfaces 34: on the under side of a heavy lever 35, centered on a fixed part. By the action on the inclined surface 34: the heavy lever 35 is pushed up until the angle at the junction of the two inclines gets over the end of the actuating-lever 31, and then the heavy lever 35, acting like a tumbler, quickly and certainly carries the lever 31 through the remainder of its stroke or movement. This completion of the movement by the heavy weight causes the clutchlever 28 to shift the clutch-sleeve 27, and thereby effect the reversal of the motion of the pinion-shaft 11, the movement of the clutch-lever 28 being effected by means of a projection 36 on one part between two projections on or the sides of a notch in the other part with as much play between them as will allow the actuating-lever 31 to reach the angle 34 of the heavy lever 35 before acting on the clutch-lever 28. The spindle 29 of the levers 28 30 31 is carriedbya bracket 37, formed on or bolted to the casting 6, and this bracket 37 and another bracket 38 are formed with bearings for the driving-shaft 26.

Instead of the building or traversing rails 8 being raised and lowered by means of racks and pinions, chains may be used, each having one end fixed to a boss or small barrel substituted for the pinion 10 and the other end being fixed to a projection at the lower part of the slide 12.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In mechanism for working, building, or traversing rails of spinning, roving, twisting, and analogous machines, the combination of the traverse-rail and a reversing-clutch adapted to be operated by the traverse-rail with a three-bevel-wheel gear in connection with the clutch and dilfereutial gear to reduce speed, all substantially as described.

2. In mechanism for working, building, or traversing rails of spinning, roving, twisting, and analogous machines, the combination of the traverse-rail having tappets, a reversing clutch-lever adapted to be operated by the tappets, and a heavy tumbler-lever to act on the clutch-lever with athree-bevel-wheel gear in connection with the clutch, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN BOYD.
